Infection Mechanics

Upon execution, DarkMystic initiates a series of malicious activities:

• File Encryption: It encrypts files, appending the “.darkmystic” extension and prepending filenames with the attacker’s email and a unique victim ID. For example, “document.pdf” becomes “[[email protected]][UniqueID]document.pdf.darkmystic”.​
  
• Persistence Establishment: The malware disguises itself as “winlogon.exe” and copies itself to the Startup folder. It creates a scheduled task to ensure execution upon user login .​Wazuh
  
• System Modifications:
  
  • Deletes shadow copies using commands like vssadmin delete shadows /all /quiet.
    
  • Disables Windows Defender Firewall via netsh advfirewall set currentprofile state off.
    
  • Modifies registry keys to disable Microsoft Defender’s real-time protection.
    
  • Drops a batch file in the Startup folder to disable Task Manager, hindering process monitoring .​Wazuh

Ransom Note

Upon encryption completion, DarkMystic alters the desktop wallpaper and creates two ransom notes:​

• info.hta: A pop-up window providing detailed ransom instructions.​
  
• Restore-My-Files.txt: A text file placed in each encrypted folder.​
  

The ransom note reads:​

Conclusion

DarkMystic (BlackBit) ransomware represents a dangerous and evolving cyber threat, capable of causing significant data loss, operational disruption, and financial damage. Its advanced encryption techniques, stealthy distribution methods, and aggressive ransom demands make it a critical concern for individuals, businesses, and IT infrastructure operators alike.

With no publicly available decryption tool and a growing history of victims left without recovery even after paying the ransom, the risk of permanent data loss is very real. Prevention remains the most effective strategy—this includes maintaining strong cybersecurity hygiene, educating users about phishing, ensuring regular and secure data backups, and implementing multi-layered defenses.

If infected, victims are strongly advised not to engage with the attackers or pay the ransom, as it offers no guarantee of file recovery and only fuels further cybercriminal activity. Instead, focus on isolating the infected systems, removing the malware using a trusted antivirus tool, and consulting cybersecurity professionals for guidance.

In a digital landscape where ransomware is increasingly common, staying informed, prepared, and vigilant is the key to safeguarding your data from threats like DarkMystic.
